Subject: tcp_write_space

Hi,

Why isn't the sk->callback_lock aquired in the tcp_write_space
callback ??

Is this intentional ?

Yes, this lock is not required in this case because tcp_write_space()
is called only from under socket lock, which is stronger than callback_lock.
This is true _only_ for TCP sockets.
